A 22-story office tower completes Liberty Mutual’s Boston campus. Façade lighting at the penthouse level illuminates limestone detailing, elegantly blending with the surrounding architecture. Shifts in architectural planes are expressed with concealed sources to highlight the depth and sophistication of the architecture. An ever-changing, glowing glass pedestrian bridge connects the tower with the existing headquarters across the street. The nighttime experience of the “light bridge” transforms a momentary connection into an experiential journey from one building to the other.
